Chargeback Alerts

Register a chargeback alert (admin)

Administrative endpoint that records a chargeback alert for a paid charge. In a single transaction it:

Refunds the charge (falling back to the manual refund queue when the PSP does not expose an API refund).
Debits the chargeback alert fee configured for the merchant (merchant_settings.chargeback_alert_fee, with the gateway default as fallback) from the merchant’s available balance and credits the gateway’s revenue balance.
Transitions the charge status to pre_chargeback.

Requires the admin.chargeback_alerts.create permission. The operation is idempotent: a second call for the same charge returns 422.

See Alertas de chargeback for the full flow, including the manual refund fallback.
